Abstract (en)
[origin: EP1335611A2] [Problem] To provide a camera with an image recording mode switching function capable of assuredly preventing the generation of a hunting upon switching the image recording mode. [Means for Resolution] An image pick-up signal obtained by a CCD image pick-up element 1 is outputted as a color video signal or a black-and-white video signal in accordance with an image recording mode through processes by an analog signal processing part 2, an A/D converting part 3, a digital signal processing part 4 and a video output part 5. A control part 6 controls all the operations of a camera including a process for determining the image record mode. The image record mode is basically determined in accordance with a luminance signal. The image record mode is set to a color image record mode under a high luminance and set to a black-and-white image record mode under a low luminance. However, when the image pick-up signal is formed under near infrared radiation even in the high luminance, the image record mode is set to the black-and-white image record mode. Whether or not the image pick-up signal is formed by the near infrared radiation is decided by analyzing the color signals of the image pick-up signal.
